[0033] According to an aspect of some embodiments of the present application, a method for data verification of a power grid graph database is provided. Optionally, the method for data verification of a power grid graph database can be applied in a hardware environment as shown in Figure 1 As shown in Figure 1 The terminal 102 can include a memory 104, a processor 106, and a display 108 (optional component). The terminal 102 can be connected to a server 112 through a network 110. The server 112 can provide services (such as application services) for the terminal or a client installed on the terminal. A database 114 can be set on the server 112 or independently of the server 112 to provide data storage services for the server 112. In addition, the server 112 can run a processing engine 116, which can be used to execute the steps performed by the server 112.

[0034] Optionally, the terminal 102 can be, but is not limited to, a terminal that can calculate data, such as a mobile terminal (for example, a mobile phone, a tablet computer), a notebook computer, a PC (Personal Computer), and the like. The network can include, but is not limited to, a wireless network or a wired network. The wireless network includes Bluetooth, WIFI (Wireless Fidelity), and other wireless communication networks. The wired network can include, but is not limited to, a wide area network, a metropolitan area network, and a local area network. The server 112 can include, but is not limited to, any hardware device that can perform calculations.

[0035] In addition, in the present embodiment, the method for data verification of a power grid graph database can also be applied in a processing device with strong processing capability without data interaction. For example, the processing device can be, but is not limited to, a terminal device with strong processing capability, that is, each operation in the method for data verification of a power grid graph database can be integrated in a separate processing device. The above is only an example, and the present embodiment does not make any limitation in this regard.

[0036] Optionally, in the present embodiment, the method for data verification of a power grid graph database can be executed by the server 112, or by the terminal 102, or by both the server 112 and the terminal 102. The terminal 102 can also execute the method for data verification of a power grid graph database by a client installed thereon.

[0037] Taking the method for data verification of a power grid graph database applied in a central processing unit as an example, Figure 2 is a flowchart of an optional method for data verification of a power grid graph database according to an embodiment of the present application, as shown in Figure 2As shown, the flow of the method can include the following steps:

[0038] In step S201, the meta metadata of the graph database is constructed according to the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, the type set of the preset connection point of the edge, the preset degree of the point, and the attribute value information of the point or the edge. The meta metadata of the graph database is the structural information of the structural metadata describing the schema of the graph database. Optionally, in the database field, the metadata is the data about the data, which can help the analyst find the target data. The metadata is the data describing the structure and the establishment method of the data in the database. In the field of graph database, the schema is often introduced to describe, that is, the description of the structure and the characteristics of the graph database, which only involves the description of the type and does not involve the specific value. In the process of visualizing the power grid intelligent business system based on the power grid special graph database, the meta metadata of the power grid graph database is innovatively introduced in the embodiment of the application. Since the power grid intelligent application has its specific input verification logic, for example, a certain device or component can only be connected to a certain device or a few devices, or a certain device can only be connected to other devices through a cable with certain electrical characteristics. The verification logic is converted into the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, the type set of the preset connection point of the edge, the preset degree of the point, and the attribute value information of the point or the edge, and the meta metadata of the graph database is constructed according to the information. It should be noted that the metadata of the database refers to the data about the data, which is the structural information of the point and edge data in the graph database. The type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, and other information introduced in this embodiment are structural information about the structural information on the basis of the structural information of the point and edge data.

[0039] In step S202, the data in the graph database is verified by the visualization client according to the meta metadata of the graph database. Optionally, the meta metadata constructed in step S201 can be used for data verification or restrictive detection in the visualization client when the terminal user of the power grid intelligent application performs data entry. In addition to the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, the type set of the preset connection point of the edge, the preset degree of the point, and the attribute value information of the point or the edge, the meta metadata can be expanded according to the input verification logic of the power grid intelligent application.

[0040] In the embodiment of the present application, the meta metadata of the graph database is constructed according to the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, the type set of the preset connection point of the edge, the preset degree of the point, and the attribute value information of the point or the edge, the meta metadata of the graph database is the structural information of the schema structural metadata describing the graph database, and the data in the graph database is checked by the visualization client according to the meta metadata of the graph database. Since the embodiment of the present application supports the original graph database server side data checking, and checks the point and edge data according to the meta metadata by the visualization client, a simple and feasible checking method is provided for checking the data in the graph database according to the power grid equipment checking logic, that is, the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, the type set of the preset connection point of the edge, and the like, thereby achieving the technical effects of reducing the processing load of the graph database server side and improving the understandability of the data. The problem of low checking efficiency of the power grid graph database in the related art is solved.

[0041] As an optional embodiment, the type set of the preset connection point of the edge includes a starting point type set and / or a target point type set; the preset degree of the point includes the degree of all type adjacent edges of the point, the degree of any type adjacent edge of the point, and the degree of all type adjacent edges or the degree of any type adjacent edge of the point with a target attribute value; and the attribute value information of the point or the edge includes the maximum value, the minimum value, the enumeration value, the illegal value, and any combination of the predicate of any attribute of any type point or edge, and the predicate is a word describing the attribute value range.

[0042] Optionally, the type set of the preset connection edge of the point, that is, the point connection edge type limiting meta metadata, introduces the type set of the edge that can be connected in the point schema definition, that is, the type of the edge that can be connected by a certain type of point; similarly, the type set of the preset adjacent point of the point, that is, the point connection neighbor point limiting meta metadata, introduces the type set of the neighbor point that can be connected in the point schema definition, that is, the type of the neighbor point that can be connected by a certain type of point.

[0043] The type set of the preset connection point of the edge, that is, the edge connection type limiting meta metadata, introduces the type of the point that can be connected by the edge in the edge schema, that is, the type set of the starting point, the type set of the target point, or the combination of the type set of the starting point and the type set of the target point that can be connected by a certain type of edge.

[0044] The preset degree of a point, i.e., the degree-related metadata of the point, introduces a degree limit for the point. The preset degree of the point includes: the degree of all types of adjacent edges of the point, i.e., the degree of all connectable edge types (edge schema) of the point; the degree of any type of adjacent edge of the point, i.e., the degree of the point specifying one or more edge schemas; the degree of all types of adjacent edges of the point or the degree of any type of adjacent edge of the point of any type and target attribute value, i.e., the degree of the point corresponding to a specific attribute value of a specific point schema, i.e., the points of the same schema can have different degree limits when the attribute values are different, and it can be limited that the degree is for all types of edges or for one or more types of edges. Wherein, the degree can refer to the maximum out-degree, the maximum in-degree or the maximum total degree (the sum of the maximum out-degree and the maximum in-degree). When performing power grid specific device data warehousing, the degree limit can be introduced for the point according to the category of the device (i.e., the schema category), the device specific model identified by a certain characteristic (such as a specific attribute value), the interface number characteristic, and the like, thereby avoiding the emergence of non-standard design.

[0045] The attribute value information of a point or an edge, i.e., the metadata about the value range of the attribute, the value range setting of a certain attribute corresponding to a certain schema can include any combination of maximum value, minimum value, enumeration value, illegal value and predicate, wherein the enumeration value refers to the limited and allowed value in the list defined at the time of creation; the illegal value refers to the value that cannot be equal to; the predicate is a word describing the value range of the attribute, such as "equal to a certain value", "greater than a certain value", "value within a certain range", etc. The above attribute value information can be combined to form the metadata about the value range of the attribute.

[0046] As an optional embodiment, the data in the graph database is verified by a visual client according to the metadata of the graph database, including: when a visual client adds an edge, verifying whether the starting point and the target point of the added edge conform to the metadata of the graph database according to the preset type set of connected edges of the point, the preset type set of adjacent points of the point and the preset type set of connected points of the edge. Optionally, according to the above metadata, the power grid business system supports data verification when the visual client is used to enter the power grid device management data. Specifically, the visual interface can contain all or part of the point and edge information in many cases, so the data verification in this step refers to the data verification of the visual client (non-graph database server side), thereby avoiding the process of verifying the data verification logic on the graph database server side, achieving the purpose of saving network overhead and server side processing resources.

[0047] When the edge is added to the visualization client, if the type set of the preset connection edge of the point is contained in the meta metadata, it is checked whether the start point and the target point of the added edge meet the requirement of the "point-connectable edge". If the type set of the preset adjacent point of the point is contained in the meta metadata, it is checked whether the added edge meets the requirement of the "point-connectable adjacent point" of the start point and the target point respectively. If the type set of the preset connection point of the edge is contained in the meta metadata, it is checked whether the start point and the target point of the added edge meet the requirement of the "edge-connectable point" of the edge. When the edge is added through the visualization interface, the visualization interface usually displays the two connection points of the added edge, and thus the above checking process can be completed through the visualization interface.

[0048] As an optional embodiment, the data in the graph database is checked by the visualization client according to the meta metadata of the graph database, and further includes: checking whether the preset degree of the point meets the meta metadata of the graph database according to the degree of the all-type adjacent edge of the point and / or the degree of the any-type adjacent edge of the point; checking whether the preset degree of the point of any type and target attribute value meets the meta metadata of the graph database according to the degree of the all-type adjacent edge of the point of any type and target attribute value or the degree of the any-type adjacent edge.

[0049] Optionally, when the edge is added, the degree limitation check of the start point and the target point of the edge is performed, that is, it is checked whether the start point and the target point of the added edge meet the preset degree of the point in the meta metadata, so as to ensure that the degree limitation of the start point and the target point of the edge meets the requirement after the new edge is added. When the edge is added through the visualization interface, the pre-determination needs to be performed to determine the condition of the check of the visualization interface. For example, after all the adjacent edges of the start point and the target point of the added edge are displayed (or the visualization interface is loaded), the data is checked according to the degree of the all-type adjacent edge of the point; for another example, after all the edges corresponding to one or more edge schemas of the start point and the target point of the added edge are displayed (or the visualization interface is loaded), the data is checked according to the degree of the any-type adjacent edge of the point; for another example, after the specific attribute value of the start point and the target point of the added edge is loaded on the visualization interface, the data is checked according to the preset degree of the point of the specific type and attribute value, and the specific content of the preset degree of the point can be referred to the description in other embodiments, which will not be described herein.

[0050] As an optional embodiment, the visualization client acquires the attribute value input by the user, and verifies the data in the graph database according to the meta metadata of the graph database by using the visualization client, and further comprises: when the attribute value is modified, verifying whether the modified attribute value conforms to the meta metadata of the graph database according to the attribute value information of any type point or edge. Optionally, the visualization client can acquire the attribute value input by the user, and when it is detected that the attribute value is modified, the data can be verified according to the attribute value information of the point or edge in the meta metadata. It can be understood that the attribute value information of the point or edge can also be verified when the point is created, and the specific content of the attribute value information of the point or edge can be referred to the description in other embodiments, which will not be described here.

[0051] As an optional embodiment, the method further comprises: expanding the meta metadata of the graph database according to the priority of the power grid equipment type; and displaying the points and edges in the graph database according to the expanded meta metadata of the graph database by using the visualization client. Optionally, the meta metadata is structural information describing the schema structural metadata of the graph database, such as the type set of the preset connection edge of the point, the type set of the preset adjacent point of the point, and the like. The meta metadata can be expanded according to application requirements. For example, priority information of the power grid equipment type is introduced in the meta metadata, that is, different power grid equipment types set by the schema or different attribute values are set with display priorities in the meta metadata. When there are too many display elements in the visualization interface, the priority of the power grid equipment type in the meta metadata can be used to determine the points and edges that need to be displayed. It should be noted that the scenario of too many display elements is, for example, that there are thousands or more point and edge elements to be displayed in the visualization interface, or there are too many attribute information to be displayed, or the screen size is smaller compared with the display elements.

[0052] As an optional embodiment, displaying the points and edges in the graph database according to the expanded meta metadata of the graph database by using the visualization client comprises: displaying the points and edges of the target priority, and not displaying the points and edges of the non-target priority; displaying the points and edges of the target priority and the points and edges of the non-target priority according to a first proportion and a second proportion respectively; displaying the points and edges of the target priority and the points and edges of the non-target priority according to a first size and a second size respectively; and when the point or edge of the target priority is selected, displaying the points or edges of the non-target priority within a preset degree range.

[0053] Optionally, when there are too many display elements, the visualization display strategy according to the priority includes but is not limited to the following examples:

[0054] (1) Only display the element types of the target priority, and do not display the element types of the non-target priority.

[0055] (2) Display a certain number of elements with high priority in a large proportion, i.e., a first proportion, and display a certain number of elements with low priority in a small proportion, i.e., a second proportion. For example, display 80% of points and edges of target priority and display 20% of points and edges of non-target priority.

[0056] (3) In terms of display effect, elements with high priority are displayed in a large size, i.e., a first size, and elements with low priority are displayed in a small size, i.e., a second size, in the case of display (e.g., in proportion).

[0057] (4) In terms of interaction, when a displayed point or edge with high priority in a certain region is clicked, points or edges with low priority that are not displayed in the region (e.g., within a preset degree range, i.e., a point with low priority is connected to a point with high priority by an edge) are displayed.

[0058] In the embodiment of the present application, the visualization client can know the size of the display region and the number of elements to be displayed, and in combination with the meta metadata information expanded in the embodiment of the present application, a suitable display strategy can be selected to display the point and edge data in the "too many display elements" scenario. Thus, hierarchical display of the visualization interface is realized, and the effect of providing more flexible visualization display information for the visualization interface is achieved.

[0059] As an optional embodiment, Figure 3 is a schematic diagram of the overall flow of a data verification method for a power grid graph database according to an embodiment of the present application. As shown in Figure 3 , the flow of the method can include the following steps:
